As the design framework informs design based on the emergent processes in real classrooms, it may present more robust and synergistic patterns of scaffolding that can withstand the in-situ interplay of various classroom constraints such as robustness of the technology, limited curriculum time, and limited energies or attention span of the students and the teacher.
Due to classroom time constraints some of the teachers gave students who were willing to participate the questionnaire to take home and complete for the next class session.
It would seem logical that instructor and peer facilitation are equally important in both phases; however, classroom time constraints necessitate the delegation of one of the phases to students.
Due to classroom and logistical constraints, the survey was designed to be short and students only could respond whether they agreed (e.g., "agree," "yes"), disagreed (e.g., "disagree," "no"), or neither agreed nor disagreed (e.g., "neither agree nor disagree," "neutral") with the questions.
Until recently, practical skills in physiotherapy curricula have been taught based on live demonstration, followed by practice and feedback, at a time and manner determined by classroom and time constraints.
The interviewee from institution Q did not have an ideal initial classroom due to institutional constraints.
This cannot occur in the classroom due to time constraints, especially when the instructor controls the pace of instruction and under largely lecture format contexts.
How can researchers in K 12 contexts stay true to the principles of rigorous evaluation designs within the constraints of classroom settings and limited funding?
Among the identified barriers to teaching these skills in biology classrooms are time constraints, the need to cover content, and the lack of validated, biology-specific assessments of critical thinking (Bissell and Lemons, 2006; Coil et al., 2010).
Furthermore, the limited amount of time available for the classroom activity posed a significant constraint on our taking advantage of the full potential of Avida-ED for authentic inquiry.
